If exiting the Rwy end at 80 to 100 kts after an RTO close to V1 is the result
I fear you may have missed my point .. perhaps my words were not well chosen ?
The reject is a seriously critical manoeuvre. Of great concern is that, for the stopping bit, the shape of the speed vs time (or distance) curve during the stop is quite steep. Ergo, if there is anything much wrong in the execution of the manoeuvre, and the aircraft ends up a bit further down the runway than intended (for a critical reject limiting runway), it will end up off the runway. Due to the high deceleration at that point, the speed may well be up in the 80-100 kt range with a significant probability of serious hull damage traversing the overrun.
So, yes, something has gone wrong .. a little distance has been squandered. It doesn't take anything bigtime, just squander a little bit of distance ..
For older certification aircraft, particularly, there is scant margin ...
